Located in the hopper 2 is an agitator 15 which 'lrevents clogging of the cereal "in the hopper. Located in the passage Way 3 there are rotating nlades 16 wxich serve the double function of Acting as a valve to prevent the travel of the vapors from the chamber 1 upwardly through the hopper, and as a dis-- trilmler for the cereal, the blades acting as a, if discharge even amounts of if 17 which conveys the Way to the screen 4. removable drawer arllllSll or flour from the eon] P it re tively W ids f into the chamber 9 o 1 w '1 eonsists of n with the jet- "wlsicl"; there shown, and WlllCh t by means oi the screen 4 projects 28 designates a container for ammonia i pregnated with ammonia vapors .\Vl1l0ll is located above the retort 24 and is i pate such formaldehyde as may -connected therewith by means of a pipe 29.

30 designates a valve for controlling the flow of ammonia, and 31 designates a jet secured to the pipe 29 and arranged to discharge into the retort 24.

Located beneaththe retort 2% there is a burner which receives its fuel supply from the source of fuel supply 13.

33 designates a stack leading from the chamber 1 to atmosphere to carry off the formaldehyde-laden vapors from the operating room. In order to control the draft for the purpose of confining the formaldehyde-laden vapors in the chamber 1 as greata length of time as possible, 1 have provided a damper 34.

35 designates a stack leading from the chamber 21 to atmosphere and preferably connects with the stack This stack 35 is also provided with a damper 30.

Supported upon the same shaft which carries the pulley 8 there is a sprocket wheel 37 embraced by a sprocket chain 38 which chain embraces a sprocket wheel 39 which is carried by the shaft which supports the blades 16. Supported upon the same shaft is a sprocket wheel 40 which is embraced by a chain all leading to a sprocket wheel l2 carried by the shaft which supports the blades 22. The shaft which supports the blades 16 carries a third sprocket wheel 43 which is embraced by a chain 44: which connects with a sprocket wheel 45 carried by the shaft which so ports the agitator 15.

In the practical operation of my 'machine, the hopper is filled with a quantity of material, such as rolled oats, which is to be treated for the destruction of grain weevil and their eggs and larvae. The machine is then set in motion, which causes the agitator in the ho )per to operate and the blades 16 to feed the screen 4 with the cereal to be treated. The screen 4 is re ciprocated to cause the cereal to travel through the chamber 1, which chamber is filled with a vapor laden with formaldehyde arising from the container 10.

The screen discharges the cereal, after being treated in theformaldehydc vapor bath, into the chamber 21, Where it-is subjected to a current of air heated and imto dissiby the cereal from the formaldehyde vapor bath. 4

1 claim:

1. In a machine for treating cereals, a chamber, means for moving cereal to be treated through the chamber, a source of supply to the cereal-moving means, a vaporizer in communication with the chamber, means located between the source of cereal supply and the cereal-moving means to prevent the escape-of vapor from the chamher, a hood in communication with the chamber arranged to receive the cereal from the moving means, air heating means, a jet,

be carried;

in communication therewith and arranged.

to discharge into the hood, and means in said hood between said jet and the cerealmoving means to prevent escape' of vapor from the chamber. 4

2. In a machine for treating cereals, a

chamber, means for moving cereal to be treated through the chamber, a vaporizer in communication with the chamber, an inlet leading to the cereal-moving. means and an outlet at the delivering end of the moving means, means located at both inlet and outlet to prevent the escape of vapor from the chamber, and means for subjecting the cereal, after having been discharged from the chamber, to a jet of heated air.

3. In a machine for treating cereals, a

chamber, having an inlet and an outlet, for

ccr ea] to be treated, means for causing the cereal to be treated to move through the chamber between said inlet and outlet, a vaporizer arranged to'discharge into said chamber beneath the body of cerealcarried through the chambc'z a controllable outlet for said vapor above the body of cereal, means located at both inlet and outlet to prevent the escape of the vapor from the chamber, and means for subjecting the cereal to a blast of hot air after having passed through the chamber.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
